Specification of Letters Patent.

Patented Jan. lll, 1916.,

Application led August '7, 1914. Serial No, 855,578A

To all whom it may concern Be it known that we, JAMES F. LEMON and SAMUEL A. MAcDoNALn, citizens off the lnited States, and residents ot' Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful iililking-lilachine, of which the following is a specication.

Thisinvention relates to milking machines and has for its objecty a particularly simple and eliicient vacuum chamber therefor, which can be readily cleaned and in which it is impossible for the milk to be drawn out through the suction pipe into the pump. i A

Other objects Will appear throughout the specification.`

ln describing this invention, reference is 'had to the accompanying drawing, which is a vertical sectional view, partly in elevation, of a preferable embodiment of our invention, the contiguous portion of a milk pail cover being also shown.

This vacuum chamber comprises Aa very tically elongated body provided with a re-,

movable closure at its lower end, an intake pipe extending into the body preferably through the top thereof and depending some distance belouvv the top, and a suction pipe opening through the top and terminating above the loiver end of the intake pipe. The suction pipe usually terminates at the inner face of the top. The body is also formed with a milk outlet located in its side and near the bottom.

l is the-body which is here shown in the form of a truncated cone open at its lower end. and closed at its top.

2 is the closure threading into the lower endet the body. n

3 the intake pipe extending` into the body l substantially centrally thereof, and terminatingr near the'center, here shown as slightly above the center.

4 1s a .pipe mounted on the top of theV chamber' l and extendingr horizontally from the pipe 3 bevond the sides of the same for connection with the tube which is connected to the parts which engage the teats of the CO'.

is the suction pipe which stands yertically on the top, this pipe being designed to be connected to the pump in the usual manner. as will be understood by those skilled in the art.

The body lis here shown as provided with vand the inner face 9 of the margins two milk of and near the bottom, the outlets being controlled by pivoted lflap valves 7. The lower sides or bottoms 8 Hat and incline downwardly and outwardly the closure 2 is conQV vexed inwardly, and is alined at its -margins with the bottoms 8 of the outlets so that the milk will have an easy path through the outlets.

The body is provided intermediate of its ends with means for engaging the margin of the wall around the hole in the cover of the milk pail, on which cover the vacuum. chamber is mounted. Said" means consists of an external annular groove l0, and the cover of the pail may be formed in two seo tions the lines of division' between the same extending diametrically through the hole so 2 that when the sections are brought together of the halves of the hole will come in the groove 10. The cover may be constructed in any suitable manner vto enter the groove 10.

Owing to the arrangement of the inlet 3 and suction pipe it is impossible for the suction to draw the milk or milk spray through the suction pipe and into the pump.

Owing to the shape of thefbody, the milk :1.

has a ready egress therethrough, and furthermore, it can be readily attached to the milk 'pail cover or inserted through the hole thereof, owing to its conical shape, and for this purpose it is only necessary that the upper portion be conical. Furthermore, o\ving to the conical form of the body, it can be readily cleaned upon the removal of the closure 2r lVhat We claim is l. A milking machine comprising a vertical elongated body open at its bottom-ami Aa lremovable closure at the lower end of the body. and inlet and suction pipes Aat 'tlv-l top of the body, the 'body yhaving a mill; outlet at the lower end of the body. substantially as and for the purpose described. .y

2. ln a milking machine. a vacuum cham ber comprising an elongated body in the form of a truncated cone, inlet and suction pipes at the top of the body, a removable closure' at the lower end of the body. and an outlet for the milk in the side of the body and near the lower end l thereof. substantially as and for the purpose specified.

In a milking machine, a vacuum chamof the outlets are outlets (3 located in the sides therer ber comprising an.v elongated body in the :torni of atruncated cone l'iaving means between its ends for' engagmg the margin of lthe wall around the opening in the cover ot' a milk pail, the body also having` an inlet extending 'throughy the top thereof substantially centrally of the body and terminating near the center otthe body, a suction pipe opening through the top and terminating at the inner face of the top, a removable closure 'for the lower end of the body, and a milk outlet located at the side of the body near lthe lower end thereof, substantially as and for the purpose described. N

1. ln a milking machine, a vacuum ehamloer coniprisinga body open at its lower end, a closure for the lower end of the body, the bodyliaving a milk inlet and a Suction pipe in its upper portion, and a milk outlet in its side and near its lower end` the bottom of the milk outlet being inclined downwardl 7 and outwardly, and the inner I'aee bt' the closure beine; convex and alinecl at its margin with the bottom of the milk outlet, substantially as and for the purpose specified.

5, In a milking machine, a vacuum chamber comprising an elongated body in the form of a truncated cone having means be tween its ends for engaging the margin of the wall around the opening in the Cover of a milk pail, the body also having an inlet pipe extending throughthe top thereof, substnntially central ot the body and terminat ing' ,near the center ot the body., a suction pipe opening through the top and terminatine; at the inner tace of the top, a removable closure for the lower end of the body, and a milk outlet .located in its side and near its lower end, the bottom of the milk outlet inclining downwardly and outw \\'ardly,.and the inner face of the closure being convex and the margin thereof being alined with the bottom et the outlet, substantially as and for the purpose set forth.

lin testimony whereof, we, have hereunto signed our names in thepresenee of two attesting witnesses, at Syracuse, in the county of Onondaga, in .the State of New York, this 24th day of July, 1914. JAMES l?. LEMON. y SiiiMl EL fr. MAGIDUNLD. `Witnesses z,
